Chapter 2: Managing The Xsr; Utilizing The Command Line Interface; Connecting Via The Console Port On Xsr Series; Using The Console Port For Dial Backup On The Xsr 1800 Series - Enterasys Security Router X-PeditionTM User Manual

The XSR can be managed via three interfaces with varying levels of control: the Command Line
Interface (CLI) for full configuration, performance and fault management; the Simple Network
Management Protocol (SNMP) for remote monitoring and firmware upgrades, and the Web for
gathering version information.

Utilizing the Command Line Interface

The Command Line Interface (CLI) is a widely used tool to access and control configurable
parameters of the XSR. You can access the CLI three ways:
• Directly connect to the Console port via an asynchronous terminal
• Over the network using Telnet or SSH via a LAN or WAN interface

Connecting via the Console Port on XSR Series

For ease of use when first setting up the XSR, you can directly connect the Console port to an
asynchronous terminal (via Microsoft's HyperTerminal or other program) with the following
values: 8 data bits, no parity, 9600 bps, 1 stop bit, flow control - none. Because the Console port is
wired as a DCE with a DB-9 connector, a DB-9 null modem cable is needed to attach a standard PC
COM port to the Console port.
Although a login (admin) is required to make this connection, for additional security you can later
delete the admin user as well as disable Telnet sessions through the Console.

Using the Console Port for Dial Backup on the XSR 1800 Series

Optionally, you can set up the Console port as a dial-in WAN interface for dial backup purposes
(refer to the following Caution). This option is avaialable only on the XSR 1800 series. For details,
see Chapter 3 of the XSR Getting Started Guide.
When you enable the Console port as a WAN port, you can no longer directly
Caution:
connect to it because it is in data communication mode. Your only access to the CLI will
be to Telnet/SSH to an IP address of a configured port. Also, if
set up any of the ports properly and sets up the console port as a serial port, you will no
longer be able to login and will have to press the Default button (1800 Series) to erase
your configuration. If you opt to connect a modem to the Console port with the required
straight-through cable, configure the sample settings described below.
Note: This feature is not supported on the XSR 3000 Series.
